To all 'whom it'may concern-.-

Be it known that we, JOHN FRASER, a citivzen of the United States of America, residing in Hackensack, in the county of Bergen, in the 'State of New Jersey, and THOMAS GRAY,

a subject of the King of Great Britain and Iceland, residing in Paterson, in the county Oi" Passaic, infthe State of New Jersey, have invented certain new and-useful Improvements in Machines for Edging Metal Plates,

the following is aspecification.

Thi ,ntion relates'lzto-ga machine more partie ly intended for use in the manufacture o i'netal pipes with-rivetless longitudinal joints from metal'plates, and the invention consists in an improved construction of machine for the upsetting and planing of the longitudinal edges of the plates by means of which the rivetless joints are produced.

In the accompanying drawings 1n which is v shown a machine embo ying our invention,

Figure 1 is a transverse section on the line 1-1, Fig. 2; Fig. 2 is a side elevation; Fig. 3 is a longitudinal section on the line 3 3, Fig. 1; Fig. 4 is a view on a smaller scale, showing a change of adjustment; and Fig. 5 is a transverse section of a modification.

As is customary in this class of machines, the principal elements include awork table on which the plates P are clamped by means of a clamping frame and tool carrying standards on opposite sides of the work table and plate to be operated on.

While one ,feature of our invention hereinafter described is applicable to these machines, whether the tool-carrying stands or the work table and plate constitute the traveling part of the apparatus, certain other features are applicable only to such a machine in which the work table is stationary, and in the accompanying drawings we have shown alll our improvements applied to stationary Work table apparatus.

Referring to Figs. 1, 2 and 3, the stationary work table A consists of longitudinal girders supported at their opposite ends only on foundations F, F1, (Fig. 3), so that under; neath there is a clear way nearly the l'ull length .of the work table or at least more than the length of the longest .plate to be Operated on.

8. .The side girders 6, 6, are of less height' thanuthr .'entral girder 5, 5, so as to permit of the mounting upon these side girders and braces '7,' of laterally adjustable beams 10 and removable ller blocks 9, so that by re-v moving ller blocks 9 of Ione size and replacing them by blocks of other sizes, say smaller than those shown in Fig. 1, and as shownin Fig. 4, i'or example, the table may be arranged for work on varying widths of plates P.

'Ihe clamping Atrame B, which comprises central girders 11 11, and laterally adjustable sidel girders 12, 12, are secured tOGether at their opposite ends by transverse eams 13, which in turn are supported by the stationary table A through .the medium ot'any suitable hydraulic jacks J, by which the whole clamping frame B maybe raised and lowered for the insertion, clamping and-withdrawing of the plates P to be Operated on, as will be readily understood.

D, D, are the two tool carrying standards on opposite sides of the work table, E being suitable tools to operate upon the edges ofthe plates P to plane and upset them. -1hese standards D, D, are connected together both above and4 below the Work table by suitable means. In the drawings I have shown threaded bars G, G1 lfor the purpose, with nuts 14, permitting of lateral adjusT ment of the standards to operate on diii'erent widths of plates P. To permit of' this, the toolsupporting part of cach standard is made to project inwardly, or overhang, as shown at 15, Fig. 1, so that when the work table and clamp are adjusted for operation upon the narrower widths of plates P, the tools may be carried inwards over the non-adjustable part of the work table, as illustrated in Fig. 4;. 'this is a matter of practical importance in machines of this character, whether the work tableor the tool carrying standards be the traveling part.

In our present machine, icre illustrated, the' tool-carrying standards constitute the traveling` carriage, and to permit of this whileat the same time permitting lateral ad-A opposite ends, as before described, a` 'clear way 1s left for the tie rods G1 in the travel of the tool carriage.

The projecting parts 15 of the standardsl D and the sides of the beams 10 may be proided with suitable bearing faces 26, 27,

While we do not wish to restrict ourselves to any partlcular construction of feed mechanism for the traveling of the tool carriage, 1

we have shown in the drawings one which is applicable. It comprises two longitudinal screw-threadedV rods K each mounted in fixed bearings 18, 19 at opposite ends of the machine, and threaded into suitable feed nuts 20, carried by the standard D. The

l -feed screws may be driven by any suitable mechanism, as for example, a worm andl worm wheel motion 21, Fig. 2. Between assuming the tool-carrying standard D in Fig. 2 to be travelingin the direction of the arrow, bythe rotation of the feed screw K, the

ange 24' has come into contact with the head 23 of the rod 22 and is drawing the supe porting pedestal M after it, so that by the time the standard has reachedthe end of its travel, the pedestal M will be about midwaybetween the bearing 18 and the standard D. Meantime, the forward side of the standard D has come into contact with the pedestal 19 and pushed it ahead. On the return travel of the tool carriage, the reverse action will take place, that is, the lost motion con-v nections between the standard D and pedes-l tals will permit both pedestals tostandstill for the first part of the traverse, and then the pedestal 19 will be drawn after the standard at a suitabledistanceA to support the screw feed rod and the pedestal 18 will be pushed ahead out of the way In Fig. .5, we have shown a slightly modiv fied form of our machine, in which instead of having filler pieces between the beams 10 and the central girders 5, 5, we provide re movable filler pieces 29 bolted to the standards D, D, between the latter and the 'girders 61 of the work table.y The girders 61 are prolower part of the ta labove the work table.

vided with bearing faces 28. The lateral adjustment of the standards can be effected bychanging the size of filler pieces 29 and by laterally adjusting the beams 10 of the work table and the girders 12 of the clamping frame, as before. w -We claim as our-invention- -1. A machine for edging plates, having a work table' and clam ing frame 1n combination-with transverse y adjustable standards having laterally projecting toolcarrying parts adapted to overhang the table when the standards-are adjusted inwardly to work on ysmall size plates.

2. A machine foredging plates, having a work table and clamping frame, the latter and the upper part of the table being laterally adjustable for different Widths of plates,

in combination with transversely adjustable standards having laterally projecting toolcarrying vparts adapted to overhan the le when clamping members and the upper part of the table areadjusted inwardly to Work on:

small sizes of plates.`

3. Amachiney for edgin plates, having a stationary work vtablean clamping frame, in combination with traveling tool-ca v standards on'opposite sides of the bed an means for tyin together the said standards both below an above the Work table.

4. A ymachine for edging plates, having a stationary Work table and fixed supports for its o posite ends, leaving a' clear way underneat to near the ends of the table and a clamping frame, in combination with traveling tool carrying standards on opposite sides of the bed and means for vtying together the said standards both below and above the work table. v

5. A machine for edging plates, having a stationary Work table and a clamping frame, in combination with'to'ol carrying standards and laterally adjustable ways extending longitudinally of the table and upon which said' standards may travel, and means for tyin together the said standards both below and In testimony whereof we two subscribing Witnesses. 1
